Noctua NH-U12S Redux CPUクーラー ユーザーマニュアル

導入

The Noctua NH-U12S Redux is a high-performance CPU cooler designed for efficient and quiet operation. It features a slim 120mm heatsink and an NF-P12 redux-1700 PWM fan, ensuring excellent compatibility with various PC components and effective heat dissipation. This manual provides essential information for the setup, operation, and maintenance of your NH-U12S Redux CPU cooler.

製品の特徴

• 合理化されたデザイン: A more affordable version of the award-winning NH-U12S heatsink.
• 高い互換性: Slim 120mm size ensures excellent case, RAM, and PCIe compatibility, fitting most tower cases (158mm height) without overhanging RAM slots or blocking PCIe on most ATX and Micro-ATX motherboards.
• 静かな動作: Equipped with a quiet NF-P12 redux-1700 120mm fan with PWM for automatic speed control, providing high cooling performance under load and near-silent operation at idle.
• 簡単なインストール: Includes the renowned SecuFirm2 mounting system for straightforward installation.
• Pre-applied Thermal Compound: Comes with high-end NT-H1 thermal paste pre-applied for convenience.
• Broad Socket Support: Compatible with Intel LGA1851, LGA1700, LGA1200, LGA115x and AMD AM5 & AM4 sockets.

セットアップとインストール

Before beginning installation, ensure your system is powered off and disconnected from the power source. Refer to your motherboard's manual for specific CPU socket information.

インストール前のチェックリスト:

• Verify compatibility with your CPU socket (Intel LGA1851, LGA1700, LGA1200, LGA115x; AMD AM5 & AM4).
• Ensure sufficient case clearance (158mm height required for the cooler).
• 必要なツール（例：ドライバー）を用意します。

インストール手順:

1. マザーボードを準備します。 For Intel sockets, install the included backplate and mounting bars. For AMD AM4/AM5, use the motherboard's stock backplate and attach the Noctua mounting bars.
2. サーマルペーストを塗布します。 The NH-U12S Redux comes with NT-H1 thermal paste pre-applied to the heatsink base. If reapplying, ensure the CPU surface is clean before applying a small amount of thermal paste to the center of the CPU IHS (Integrated Heat Spreader).
3. ヒートシンクの取り付け: Carefully place the heatsink onto the CPU, aligning the mounting screws with the stand-offs or mounting bars. Tighten the screws evenly until secure. The spring-loaded screws prevent overtightening.
4. ファンを取り付ける: Secure the NF-P12 redux-1700 PWM fan to the heatsink using the provided fan clips. Ensure the fan is oriented to blow air through the heatsink fins towards the rear exhaust of your case.
5. ファンケーブルを接続します: 4 ピン PWM ファン ケーブルをマザーボードの CPU_FAN ヘッダーに接続します。

操作手順

The NH-U12S Redux is designed for optimal performance with minimal user intervention thanks to its PWM-controlled fan.

ファン速度制御:

The NF-P12 redux-1700 PWM fan automatically adjusts its speed based on CPU temperature, ensuring efficient cooling when needed and quiet operation during lighter loads. This is managed by your motherboard's BIOS/UEFI settings. You can typically configure fan curves in your motherboard's software or BIOS to fine-tune the balance between cooling performance and noise levels.

騒音レベル:

The cooler operates at a low noise level of 25.1 dB (A) at maximum speed, making it suitable for quiet computing environments. At idle, the fan speed will reduce significantly, resulting in near-silent operation.

冷却性能:

This cooler is highly effective at dissipating heat from modern CPUs, maintaining stable temperatures even under heavy loads. Its design ensures consistent performance for both Intel Core and AMD Ryzen processors.

メンテナンス

定期的なメンテナンスを行うことで、CPU クーラーの寿命が長くなり、最適なパフォーマンスが確保されます。

クリーニング：

• Periodically clean dust from the heatsink fins and fan blades using compressed air or a soft brush.
• 清掃する前に、システムの電源がオフになっており、プラグが抜かれていることを確認してください。
• Hold the fan blades gently to prevent them from spinning rapidly during cleaning with compressed air, which can damage the fan bearings.

サーマルペーストの再塗布:

While the pre-applied NT-H1 thermal paste offers excellent long-term stability, if you ever remove the cooler or notice significantly higher temperatures, it is recommended to clean off the old thermal paste from both the CPU IHS and the heatsink base using isopropyl alcohol and reapply a fresh layer of high-quality thermal compound.
